The hind body part, containing the internal organs and has the ability to expand and contract in accordance with the condition of the spider. Spiders have a pair of pedipalps which perform sensory roles, can manipulate their food and are used by the males in mating.

Tarantulas are mygalomorphs suborder Orthognathaand thus they have jaws that move forward and down rather than sideways and together, which is characteristic of araneomorphs [suborder Labidognatha]. Tarantulas are distinguished from other mygalomorphs by a collection of traits that include not only their size and hairiness but also their two pairs of book lungs and their three-segmented spinnerets.
Tarantulas comprise a group of large and often hairy spiders belonging to the family Theraphosidae. Currently, about 1, species have been identified. Some of the more common species have become popular in the exotic pet trade.

Bird-eating spiders, otherwise known as mygalomorphs, are best known for their deadly representatives such as the large hairy tarantula and the Australian funnel-web. But despite their name most of these creatures are small and live quietly in silk-lined burrows, trapping nothing more impressive than the occasional insect. They have named it Rosamygale grauvogeli Palaeontology, vol 35, p Previously, the earliest known mygalomorphs, described inwere about million years old.
Tarantulas are part of the family of spiders called Hairy Mygalomorphs. These are the spiders that, scientists believe, have been around for millions of years and have not changed much in that time! There are around kinds, or species, of Tarantulas.
Trapdoor spiders are robust and hairy, living in tubes protected by a small camouflaged door from where they attack their victims. This group, with sixteen families and more than 2.
